PUSH-BUTTON CATCH.

.Application llled December 4, 1926. Serial No. 152,549.

This invention relates vto push button latches of the t wherein thelatch is 0perated by apu button which extends outwardly in a positionwhere it may be conveniently operated simultaneously with the graspingof the handle or knob of the door on which the latch is used.

In the use of latches of thstype the handle or knob of the door usuallyincludes a cap containing the ush button and fitted t0 the outside ofthe oor. The push button is secured to the end of the actuating memberfor the latch. The latches are made in more or less standard size and itis necessary to accommodate this size to different thicknes'ses ofdoors. In adju-sting latches of this type to the different thicknesses.of doors great diiiiculty has been experienced in maintaining properrelative positions of the ca and button.

t is accordingly an object of this invention to provide a latch of thistype in which the desired relation between the cap and the push buttonmay be simply and easily maintained.

. It is further an object of this invention to provide a latch of thistype in which the button and cap are assembled together in the samerelative positions which it is desired that they occupy when theassembly is coinplete, the said button and cap being maintained inproper relations with each otherv during assembly.

Other and further objects of this inven tion will be apparent from anexamination of the specification and claims in connection with the accomanying drawings, wherein Fig. l is a ra mentary longitudinal section ofa latch em odying this invention.

Fig. 2 is a bottom plan view of the same. Fig. 3 is a top plan view ofthe same. Fig. 4 is a sectional view of a modification. Fig. 51s a planview. of the same. Fig. 6 is a view partly' in section of anothermodification.

Fig. 7 is a fragmentary section of another modication.

Referring to the drawings more particularly, numeral 7 indicates asleeve formin va part of a latch mechanism and extending throu h anaperture 8 in a door or the like 9. The s eeve 7 acts as the bodyportion. of the latch housing, is flattened at its inner end, as at 11,andthreaded, as at 12, from its outer end ractically to its middle orbeyond. In

.the attened'portin 11 a catch 13 is pivoted on a pin 14 transverselysecured in said portion.' An actuating rod 15 for the catch 13 extendslongitudinally of the sleeve 7 and is provided with a hook portion 16 atits inner end, the end of such hook portion engaging in a recess 17 inthe catch 13 adjacent the pivot thereof, thus as the member 15 isactuated inwardly its end acting in the recess 17 will act to releasethe catch and when said member is actuated outwardly said end will actto close the catch by moving it in a clockwise direction where it isadapted to cooperate with a suitable keeper (not shown). A spring 18surrounding the member 15 abuts at its lower end a shoulder 19 formed inthe sleeve 7 by the juncture between the flattened portion 11 and therest ofthe sleeve.

, 'lhe upper end of the s ring 18 acts on a collar 21 integral with t emember l5 and acts to move the same outwardly. The limited rotation ofthe catch 13 limits the outward movement of the member 15.

.The lower end of the sleeve 7 is provided with lateral flanges 22 sothat when the sleeve 7 is inserted in the aperture 4 its inner end willgrip the inner edge of said aperture and prevent said sleeve beingpulled all the way through. The threaded portion 12 on said sleeve isadapted to extend out ofthe outer end of said aperture 8 to threadedlyreceive a cap 23 in the form of a knob having an annular-flange 24around its outer edge adapted to be grasped manually to open the vdoor9. The outer end of the member 15 is also threaded, the threads 25preferably being of the same pitch as those on the sleeve 7. A pushbutton in the form of an extension 26 is fitted on the threads 25. Theextension 26 is adapted to extend outwardly through a central aperture27 in the outer end of the knob 23 any desired amount, the iit of thesaid extension 26 in said knob being a slidable one. The extension 26 isconnected to the knob 23 so that it will rotate therewith when thelatter is threaded on the end of the sleeve 7 causing said knob andextension to maintain their predetermined relative positions as they arebeing threaded on the sleeve and member 15 respectively. In order toconnect the extension 26 with t-he knob 23 the former is preferablyprovided with a plurality of longitudinally extending flat sides 28which are parallel with corresponding sides of \the aperture 27.

Thus regardless of the -thickness of the door 9 the relative position ofthe extension or push button 26 with respect to the knob 24, once theformer has been started on the threads 25, will not be changed no matterhow far the knob 24 is threaded on the sleeve 7 to accommodate differentthicknesses of doors, because said extension will rotate with said knoband will move longitudinally therewith as the threads of both saidextension and said knob are of the same pitch.

In Fig. 4 there is shown a modification in which the latch mechanismitself is substantially the same as in the previous embodiment. Amongthe diii'erences are that a handle 28 is provided, the sleeve 29 of thelatch mechanism extending through an aperture 31 in one end of thehandle and the cap 32 `is comparatively plain and acts t0 secure saidend over said sleeve. The other end of the handle 28 is secured by anordinary screw 33 extending into the door 34.

In Fig. 6 there is shown another modification in which the knob 35 andextension 36 for the actuating member of the latch are sustantially thesame as in the first embodiment. In this modification the sleeve 37 ofthe latch mechanism, which is otherwise the same as in the firstembodiment, is not flattened at its inner end, but is suitably securedto a rectangular frame or housing 38 in which is pivoted a latch bolt39. The latch bolt 39 may have an arcuate surface 41 adapted tocooperate with a keeper in the same manner as the latch bolt in thecopending application of Gedor W. Aldeen Serial No. 149,839, filedNovember 22, 1926. The bolt 39 is yieldingly held in latching positionas shown by a spring 42 surrounding the pivot of said bolt. In this casethe actuating member 43 is considerably longer than in the firstembodiment and is secured by a pin 44 to a rearward extension 45 on thelatch bolt. Thus as the extension 36 is pressed inwardly the bolt 39will be withdrawn against the action of the spring 42 and when the saidextension is released the latch bolt will move outwardly to engage withits keeper.

In Fig. 7 there is shown a further modification in which the sleeve 46of the latch mechanism is substantially the same as in the lastembodiment, (Fig. 6). In this modification the housing 47 secured to theend of said sleeve supports a latch bolt 48, one end of which slidablyextends through one side of said housing and is in the form of a typicallatch bolt. The other end 49 of the bolt 48 is cylindrical in form andslidably extends through the opposite end of the housing 47. A spring 51surrounding the portion 49 normally acts to hold the bolt 48 to thewhich is pivotally mounted in the housing 47. The other end of theAlever 53 is pivotally secured to the bolt 48 whereby the push button(not shown) may be ressed inwardly to withdraw said bolt an upon saidbutton being released the spring 51 will project said bolt back tooperative position. p

The principles of this invention may thus be utilized with many'different forms of locks and therefore I do not wish to be 11mited tothe details shown and described.
